<p>I agree with Simpllifried, it sounds like you have cluster headaches and should see a specialist. The reduction of pain by reducing blood flow the brain is indicative of CH. (I use that technique if I don’t have my pills with me or before they take effect.) </p>
<p>Before the use of Triptans (such as Imitrex) to treat CH, the primary abortive medicine was ergotamine - a vasoconstrictor. My doctor said the pain sensation in the orbit of the eye is caused by the pooling/accumulation of blood for some unknown reason. </p>
<p>Good luck.</p>
